AutoCAD Civil 3D software is a Building Information Modeling (BIM) solution for civil engineering design and documentation. Civil 3D is designed for civil engineers, drafters, designers, and technicians working on transportation design, land development, and water projects. Stay coordinated and explore design options, analyze project performance, and deliver consistent, higher-quality documentationall within a familiar AutoCAD software environment.
New and improved features of AutoCAD® Civil 3D® civil engineering software enable civil engineers, drafters, designers, and technicians working on transportation, land development, and water resources engineering projects to work more efficiently. AutoCAD Civil 3D 2012 includes enhanced alignment layout and tools that enable easier sharing of drafting and design standards across organizations. Corridor enhancements streamline corridor editing, and data import improvements help to simplify the creation of intelligent objects.

SCI P287: Design of Composite Beams using Precast Concrete Slabs
Author: S J Hicks, R M Lawson | Size: 1.86 MB | Format:PDF | Publisher: SCI | Year: 2003 | pages: 101 | ISBN: 1859421393
This publication provides guidance on the design of steel beams acting compositely with precast concrete slabs in multi-storey buildings. The use of hollow core or solid plank precast units offer benefits in terms of cost (the long spanning capabilities of the precast slabs lead to fewer secondary beams) as well as the advantages offered by composite construction. The design basis is generally in accordance with BS 5950-3, supplemented by recommendations from Eurocode 4 and data from tests. Particular issues affecting the use of precast concrete concern the requirements of effective shear connection and transverse reinforcement. Small-scale push-out tests, and earlier composite beam tests, have established reduction factors for the design resistance of welded shear connectors as a function of the gap between the ends of the precast concrete units, and the amount of transverse reinforcement provided.
The guidance also emphasises the importance of the design of the steel beam in the non-composite construction stage, where out-of-balance loads can occur during installation of the precast concrete units. The guidance applies to hollow core units of 150 to 260 mm depth, and to solid precast planks. A step-by-step design procedure is given for composite beams using various forms of precast concrete units, with or without a concrete topping. This is supplemented by a fully worked design example for a composite beam in a 15.8 m × 7.2 m grid, and a series of design tables for concept design.

Among different approaches that can be considered for concrete rehabilitation, bonded overlays are often the most economical alternative. The primary purpose of overlays is to extend the life of the candidate structures, either by restoring the quality and integrity of the surface and/or the re-establishing or improving the load-carrying capacity. Nevertheless, the durability of bonded overlay systems still draws concerns in the technical community because of bond sustainability problems encountered in a number of cases. At this time, there is still no accepted design approach or methodology that can warrant the practitioner a successful outcome of the repair. This State-of-Art report summarizes the findings with respect to all aspects involved in the overlaying process.

Roofs and roofing. Performance, diagnosis, maintenance, repair and the avoidance of defects. 3rd edition
Author: Harrison, H. W., Trotman, P. M. and Saunders, G. K. | Size: 7.68 MB | Format:PDF | Year: 2009 | pages: 284 | ISBN: 9781848060920
Abstract
Draws attention to the quality of construction of roofs and roofing which is necessary to ensure good performance of the fabric for the defined life of the building, and to underline potential problems and how to avoid them. Addresses provisions to accommodate climate change. Considers lightweight green roofs, modern methods of construction, roof-mounted photovoltaic systems, thermal insulation in lofts, loft conversions and single-layer membranes. Covers metal roofing, siphonic roof drainage, new materials technologies, and finishes. Relates all roofs’ basic functions.

This part of ISO 22965 applies to concrete for structures cast in situ, pre-cast structures and structural pre-cast products for buildings and civil engineering structures. The concrete can be mixed on site, ready-mixed concrete or produced in a plant for pre-cast concrete products.
This part of ISO 22965 applies to concrete compacted to retain no appreciable amount of entrapped air other than entrained air and to normal-weight, heavy-weight and light-weight concrete. Other International Standards for specific products, e.g. pre-cast products, or for processes within the field of the scope of this standard can require or permit deviations from this part of ISO 22965. This part of ISO 22965 specifies the properties of constituent materials, the production of concrete and the compliance system of concrete.
This part of ISO 22965 does not apply to:
⎯ concrete with a maximum aggregate size equal to or less than 4 mm or 5 mm (mortar),
⎯ aerated concrete,
⎯ foamed concrete,
⎯ concrete with an open structure (“no-fine aggregate” concrete),
⎯ concrete with a density less than 800 kg/m3,
⎯ refractory concrete.
This part of ISO 22965 does not cover health and safety requirements for the protection of workers during production and delivery of concrete.
